NOVELTY - Fiber prepared by mixing graphene having a particle size of less than 1 mu , sulfonic acid, carbon nanotubes, and surfactant at a ratio of 1-5:1-5:1-5:1 and then stirring, mixing, dispersing the mixture to obtain conductive particles, adding 5-30 wt.% of polyester powder to the conductive particles, granulating the obtained mixture using twin screw granulator to obtain superconductive graphene base particles, and spinning the superconductive graphene base particles, is claimed. USE - Fiber. ADVANTAGE - The fiber can be easily prepared with less labor and in an energy-efficient manner.
